Abstract
Systems, apparatuses, and methods are described for wireless communications. Network slicing may be used to provide services for a wireless device. A network slice may be determined for the wireless device based on a required bandwidth for the network slice and/or charging information for the network slice.
Claims28
A method comprising:
- receiving, by a policy control function (PCF) from a first network entity, a first message indicating a request for a network slice for a wireless device, wherein the first message comprises:
- a required bandwidth of the network slice;
- and
- charging information for the network slice;
- determining one or more policies based on:
- the required bandwidth of the network slice;
- and
- the charging information for the network slice;
- and
- sending, by the PCF and to a session management function (SMF), a second message indicating a request to establish the network slice for the wireless device, wherein the second message comprises an indication of the one or more policies.
